TYPE: HAS-2N
SEMI -AUTO SYNCHRONISING RELAY
SPANDING : 380-440 VAC
1114320011B
1114320002B
The DEIF HAS-2N is a semi-automatic synchronising relay designed to manage the paralleling of generators within marine power management and control systems. Operating across a voltage range of 380–440 VAC, this relay facilitates the synchronisation process by monitoring and matching generator output conditions before closing the breaker, reducing the risk of out-of-phase connection and associated damage to shipboard electrical equipment. As a core component in marine control system architecture, the HAS-2N supports reliable and efficient power distribution onboard, making it an operationally critical device for vessels dependent on stable multi-generator configurations.
Key Features
✓ Semi-automatic synchronising function enables controlled generator paralleling with reduced manual intervention, supporting safer and more efficient power changeover.
✓ Rated for operation at 380–440 VAC as stated in the product data; additional technical parameters such as frequency range and response time are subject to confirmation based on unit configuration.
✓ Designed for integration within DEIF power management and generator control panel architectures; compatibility with specific panels or controllers should be verified against the vessel’s system drawings.
✓ Intended for installation in switchboard or generator control panel enclosures in the engine room or power generation spaces; mounting configuration and environmental ratings are typical for marine panel-mount relay assemblies.
✓ Replacement and retrofit considerations should include cross-referencing the part numbers 1114320011B and 1114320002B against the existing system configuration to confirm direct compatibility prior to installation.
Marine Applications
✓ Generator paralleling and load sharing systems on commercial cargo vessels, tankers, and bulk carriers operating multi-generator power plants.
✓ Offshore support vessels and platform supply vessels where reliable power management and synchronisation are critical to dynamic positioning and hotel load operations.
✓ Passenger ferries and ro-ro vessels requiring seamless generator changeover to maintain continuous power supply to propulsion and safety systems.
✓ Drill ships and offshore installations utilising DEIF-based power management systems where precise synchronisation control is essential to operational integrity.
✓ Naval auxiliaries and government vessels with structured power management panels incorporating DEIF control and protection relay equipment.
